I want to get intersection line between top plane and front plane.
I have tried with the command "intersection curves" but it doesn't allow me to select the planes as surfaces. can somebody help me?
if you want the intersection line as an axis just go to reference geometry, then click axis and then select the planes u would get the intersection line as an axis.
You have many options, open a sketch on one one of them and then choose the other for the 'Intersection Curve'.
